SIGHT FOR FIREARMS.

Specification of Letters Patent. Patented Sept, 19, 1916.

Application filed January 10, 1916. Serial No. 71,324.

To all whom it may concern Be it known that I, BRIAN C. BULLEN, acitizen of the United States, and a resident of Paterson, in the countyof Passaic and State of New Jersey, have invented a new and ImprovedSight for Firearms, of which the following is a full, clear, and eXactdescription.

This invention relates to sighting devices for firearms and has for anobject the provision of an improved arrangement to be used in targetshooting whereby more accurate firing may be produced.

Another object in view is to provide an adjustable circular front sightso as to encircle the bulls-eye when the device is in use.

A still further object in view is to provide a sighting device at thefront and rear of the firearm which may be adjusted to produce any sizedopening so as to shut out all undesirable rays of light while allowingthe eye to view the bulls-eye and a small space around the same.

In the accompanying drawing: Figure 1 is a plan view of an irisdiaphragm; Fig. 2 is a plan view of an iris diaphragm with a baseconnected thereto forming certain features of the invention; Fig. 3 is aside view of a rifle and target, certain parts being shown inperspective, illustrating the use of the sights thereon.

Referring to the accompanying drawing by numerals, 1 indicates "anordinary iris diaphragm which is adapted to be soldered or otherwiserigidly secured to a standard 2, as shown in Fig. 3, which standard maybe adjustable and which standard is .also pivotally mounted at 3 so asto be moved out of the way or up into an operative position. Anoperating arm 4 of any desired structure is provided for the diaphragm 1whereby the opening may be increased or decreased as preferred. As shownin Fig. 2, and also on the front of the rifle shown in Fig. 3, the irisdiaphragm structure 5 is provided with an arm 6 at one side for openingand closing the shutters of the diaphragm. A base 7 is rigidly securedto the diaphragm in any suitable manner so as to be fitted on to thefront of the rifle barrel in correct position.

As shown in Fig. 3, a target 8 is disclosed provided with a bulls-eye 9,the arrange ment being such that when a person using the rifle looksthrough the iris diaphragms 1 and 5 the bulls-eye will be seen and acircle of white 10 will also be seen around the bulls-eye. The irisdiaphragm 1 at the rear of the rifle is used in the capacity of what isknown as a peep-sight, while the iris diaphragm 5 at the front isadjusted so that a person looking through the peep-sight at the rearwill look through the opening at the iris diaphragm 5 and will see thebullseye 9 1n the center of a white circle. This arrangement of sightsis preferable for only comparatively short distance, as for instance,from 100 yards to 800 yards. From this it will be observed that thefront sight will, in a certain sense, frame the bulls-eye .and theentire bulls-eye will be seen regard less of the distance. WVhen thedistance is short the iris diaphragm 5 is adjusted so that the openingtherein will be of a proper size to merely disclose the bulls-eye and aslight space around the same, which is also true when the bulls-eye isat a great distance.

In the use of ordinary bead sights at the front it is usually necessaryfor part of the sight to obscure part of the bulls-eye in or der tocorrectly sight the rifle, and in doing this the bulls-eye is oftenobscured to such an extent as to cause the shot to be directed at someother spot. By providing an adjustable diaphragm structure having aninfinite adjustment the entire bulls-eye may be observed and a slightclear space around the same which, when thus observed, insures therifleman that his sight is correct.

What I claim is:

1. In a' sight of the character described, the combination with a rifle,of a sighting member .at the rear of the rifle, an iris diaphragm at thefront of the rifle. said diaphragm being provided with a foundation orbase connected to said rifle and with an operating lever for producingany desired aperture.

2. In a device of the character described, the combination with a rifle,of an iris diaphragm front sight, and an iris diaphragm rear sight, theiris diaphragm front sight being such as to cause the bulls-eye to beencircled and framed when the rifie is in use.

3. In a sight of the character described,

a peep-sight arranged at the rear of the bulls-eye on a target and aslight open rifle, and an iris diaphragm arranged at space around thebulls-eye in case the rifle the front of the rifle, sald iris diaphragmis correctly aimed.

being formed With a base and means for BRIAN C. BULLEN. adjusting theshutters of the diaphragm Witnesses:

whereby a person looking through the peep VICTOR C. BULLEN,

and through the front sight may see the J. D. BIROHENOUGI-I.
